About BTU·inch per Hour-Square Foot-Fahrenheit (BTU·in/(hr·ft²·°F))
An imperial thermal-conductivity unit (≈ 0.1442 W/(m·K) per NIST SP 811 = exactly 1/12 of BTU/(hr·ft·°F)) used almost exclusively for US building-insulation materials. The peculiar 'inch in the numerator' construction lets the unit cancel directly into R-value per unit thickness: an insulation product with k = 0.25 BTU·in/(hr·ft²·°F) achieves R-4 per inch of installed thickness (an R-19 wall = 19/0.25 = ~5 inches of that product). BTU·in/(hr·ft²·°F) is the unit on fiberglass-batt packaging (Owens Corning, Johns Manville, Knauf), rigid-foam-board labels (Dow, Owens Corning Foamular XPS, Dow Thermax polyiso), spray-foam (BASF Walltite, Demilec, Lapolla) data sheets, mineral-wool batts (Rockwool), cellulose loose-fill, and all US Department of Energy ENERGY STAR insulation prescriptive R-value targets. Reference values: fiberglass batt 0.27 BTU·in/(hr·ft²·°F) = R-3.7/in; XPS rigid-foam 0.20 = R-5/in; closed-cell spray foam 0.16 = R-6.5/in; aerogel 0.10 = R-10/in.
About Watt per Centimeter-Kelvin (W/(cm·K))
A thermal-conductivity unit equal to exactly 100 W/(m·K), used in semiconductor packaging engineering, thermoelectric materials research, and ultra-high-conductivity material characterization where W/(m·K) values would be inconveniently large. Reference values: diamond (single-crystal CVD) 10-22 W/(cm·K) — the highest natural-material thermal conductivity known, exploited in laser heatsink applications and CPU integrated heat-spreader research; graphene single-layer 30-50 W/(cm·K) (highest measured of any 2D material per Nature Materials papers); pyrolytic-graphite in-plane direction 16-19 W/(cm·K); silicon carbide (SiC) for high-power semiconductors 3.7 W/(cm·K). Solid-state-device thermal-interface-material (TIM) datasheets per JEDEC JESD51-series thermal-test standards, semiconductor-package thermal-resistance specifications, and thermoelectric figure-of-merit ZT calculations sometimes use W/(cm·K) for compactness. Convert W/(cm·K) to W/(m·K) by multiplying by 100; to BTU/(hr·ft·°F) by multiplying by 57.78.
